Why? The "splash" comes from the crank counterweights and rod ends going through
the oil in the sump. A pre-oiler pulls oil from the sump and moves it through
the passages to make sure the journals and bearings are lubricated at start.
Seems to me that the "splash" will happen just as fast either way.
